Yeah, that load is a good everyday bear stopper. I used to use some 300grn JSP's for my .454. I shoot almost all cast now.
The raging bull does have a large grip, I have big hands so the grip fits me well, but my fingers aren't very long, so I couldn't have the trigger much farther away in double action. The ultralite throws you off, because the frame is the same size, but it is only 28 oz's, which seems even less in comparison to the size. But it's great for hiking and mountaineering.
